1. What is Actual Temperature of Real Gas?

Definition: This calculator computes the actual temperature of a real gas using Clausius parameter c, critical parameters, and reduced temperature.

Purpose: It helps in thermodynamics calculations where real gas behavior deviates from ideal gas laws.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Temperature of real gas (Kelvin)
• \( c \) — Clausius parameter c
• \( V_c \) — Critical volume (m³)
• \( P'_c \) — Critical pressure (Pascal)
• \( T_r \) — Reduced temperature (dimensionless)
• \( [R] \) — Universal gas constant (8.314 J/mol·K)

Explanation: The formula combines critical parameters with reduced temperature to calculate the actual temperature of a real gas.

3. Importance of This Calculation

Details: Accurate temperature calculation is crucial for designing chemical processes, predicting phase behavior, and modeling real gas systems.

4. Using the Calculator

Tips: Enter all required parameters. Critical volume and pressure must be positive values. Reduced temperature is typically between 0 and 1 but can be higher.

5. Frequently Asked Questions (FAQ)

Q1: What is Clausius parameter c?
A: An empirical parameter characteristic to equation obtained from Clausius model of real gas.

Q2: How do I find critical parameters?
A: Critical parameters are substance-specific and can be found in thermodynamic tables or databases.

Q3: What is reduced temperature?
A: The ratio of actual temperature to critical temperature (T/T_c).

Q4: Why use real gas equations?
A: Ideal gas law becomes inaccurate at high pressures or low temperatures where real gas behavior deviates.

Q5: What are typical units for this calculation?
A: Use SI units: m³ for volume, Pa for pressure, and Kelvin for temperature.
